> the symptom is the cluster comes to a dead halt.  Lookups on meta don't seem to work,
and the regionserver carrying .META. goes hot - using 800% CPU or more, driving system LA
up really really high (I've seen it as high as 26).  Thread dumps seem to indicate every IPC
handler is stuck in Bytes.binarySearch().
